In English
It is the duty of every young student to recognise every bad idea or thought that sprouts in his mind and exterminate it completely. Mind is like a mad monkey and you should not surrender to it. You should control the mind and keep it under your direction. You should not be prepared to yield to all the desires that sprout in your mind. As soon as a thought comes into your mind, you should examine whether it is a good thought or a bad thought.
